Joerg Sprave has in the end build up an flexible - powered arm that even the burly slingshot master can barely handle when the trigger ’s pulled . It ’s a hand-held trebuchet ( a eccentric of mangonel ) that flings circular saw blades for one C of feet , and itlooks almost as terrifying to yieldas it is to be in the weapon ’s crosshairs .
Accuracy is n’t this institution ’s primary feature , but Joerg still manages to take down a mannikin , standing rough half a football field of view ’s duration away , with a spinning proverb leaf blade that graze its arm . A more useful coating seems to cut back trees without the need for a ladder , as the flying blade easy rive off small branches as it fly through the melody . You ’ll just need to check that you do n’t in reality have any neighbor , as those vane have to come down somewhere .
